Is a reese 15K?? I have this hitch, and after a while it started doing that. I found that at some time I had not seated the bar all the way either hooking up or unhooking. I found this bar not closing all the way. Took the hitch out took a large and I mean a LARGE hammer , and knocked it back into place. This went away for me. I now make certain that the king pin is free and in place. It happened one time when I had the trailer too high and high hitched it be came apparent real quick, put down the landing geat pulled the lever and lowered the unit more. If you do not have a nylon ring I would put one of these into place. I have seen where some dealers have not installed the rails right, and they have backed off check the mounting bolts here also
